t * 3 d) What is the age of the rocks above the lava flow? ▾ Question #2 The age of the earth is thought to be the same as the age of the oldest meteorites found on Earth. The oldest meteorites have nearly equal amounts of 238U and 20 How old is the Earth -- explain. ▾ Question #3 Carbon-14 is constantly being produced in the upper atmosphere, and the amount i equilibrium. As long as an organism is alive, it keeps its carbon isotopes in balance with the atmosphere, but as soon as it dies, it stops taking up new 14C, and so the geologic clock starts. You found a shell buried in sedimentary layers, which has 6% o its original 14C left. Determine the age of the shell.

7 3 d) What is the age of the rocks above the lava flow? ▾ Question #2 The age of the earth is thought to be the same as the age of the oldest meteorites found on Earth. The oldest meteorites have nearly equal amounts of 238U and 206Pb. How old is the Earth -- explain. ▾ Question #3 E Carbon-14 is constantly being produced in the upper atmosphere, and the amount if in equilibrium. As long as an organism is alive, it keeps its carbon isotopes in balance with the atmosphere, but as soon as it dies, it stops taking up new 14C, and so the geologic clock starts. You found a shell buried in sedimentary layers, which has 6% of its original 14C left. Determine the age of the shell.
